Title: Wood working machine
Inventor: EKDAHL IVAR
IPC: B23Q16/00
Filed: 1962-04-30
Abstract: 1,010,098. Woodworking. A.B. SIGFRID STENBERG. April 30, 1962, No. 16464/62. Heading B5L. The carriage 4 of a woodworking machine is movable by a fluid-pressure cylinder 1 over predetermined distances under the control of push-button switches or of an automatic programme control device and the control means comprises a bar 6 with an adjustable stop 24 operating a valve knob 25 controlling fluid to the cylinder 1 and adjustably - positioned switches 11 which are operable by an abutment 9 on a rail 5 connected to the carriage; the cylinder drives the carriage until the abutment 9 operates the particular switch 11 that has been energized by the push-buttons or programme control and the rail 5 and bar 6 are then coupled to move together so that the stop 24 causes the valve 25 to reverse the flow of fluid to the cylinder. When a switch 11 is operated by the abutment 9, a relay is energized to supply compressed air to a cylinder 15 so that a hook 17 is withdrawn from a lever 20, allowing it to fall into a slot 23 in the bar 6 and to bring a projection 22 into the corresponding one of several notches 8 in the rail 5 and thus couple the rail and bar together. Inclined surfaces at the end of the bar 6 control the flow reversal valves so that the pressure supplied to the cylinder 1 at the ends of the stroke increases or decreases slowly. To prevent too rapid reversal at the other end of the stroke the air pressure is adjusted by a conduit 31 connected to a tube 32 in which a rod 34 having a flattened portion or notch is slidable, the rod being connected at 35 to an element 3 connected to the carriage 4. If it is desired to move the carriage manually, the cylinder 1 and control means can be pivoted about pins 38 into a vertical non-operative position, after releasing the connection 3 to the carriage.

Patent GB-553007-A (GB)
Title: Improvements in and relating to maximum demand meters
IPC: G01R11/60
Filed: 1941-12-30
Abstract: 553,007. Measuring currents; indicating apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Dec. 30, 1941, No. 16761. Convention date, Jan. 4. [Class 37] [Also in Group XIX] A thermally-operated, maximum demand current indicator comprises a bimetal spiral 10 heated by unit 13 and compensated for ambient temperature by a spiral 14, both spirals acting on a shaft 11 geared to a shaft 20 on which is fixed a stop 21. A dog 19, loose on the shaft 20, is urged by spring 22 against stop 21 and operates a pointer 17 frictionally mounted on its carrying shaft and moving over a scale 18. Pointer 17 operates, through a stop 30 and spring 29, a further pointer 25 moving over a scale 34 and adapted to operate through a pawl 31 and gearing 32 an integrator 33 when reset to zero against a stop 28. In this resetting operation the pointer 17 is also reset to zero against a stop 26 and the resetting means is so arranged that, when retracted, the pointer can move back to a new correct position without overshooting. The resetting means comprises a crank 27 which engages pointer 25 or, if no integration and hence no pointer 25 is desired, the pointer 17 and is rotated slowly through 360 degrees anti-clockwise by a geared sector 36 oscillated about shaft 40 by means of a rod 37 taking in an eccentric groove 38 in a gearwheel 39. A further gearwheel 41 rotates 39 through one turn when itself rotated through three turns by a lever 44 which normally is sealed in a slot 45 in a pillar 46. In order to arrest the crank 27 after a complete turn, a slidable rod 48 having a squared end engaging a slot in sector 36 and the other end engaging in the pillar 46, has an upstanding arm 47 which, after a half-turn of wheel 39, Fig. 2, is hooked up by a finger 51 and cammed into a recess in the wheel 39 until finally it engages a wall 52. to arrest the wheel 39. When lever 44 is replaced in slot 45, it pushes the rod 48 so that arm 47 is again moved clear. Owing to the graduations on scale 18 being crowded together at the lower end of the scale in Fig. 4, and since the gearing 32 provides uniform transmission, scale 34 is made even and coincident with scale 18 at the middle and upper parts to ensure accuracy of integration. The stop 28 has therefore to be located beyond stop 26, the spring 29 allowing of this extra movement in resetting. A transmission arrangement between the two pointers is described to suit a closed upper and lower end of scale 18, Fig. 6 (not shown). In the case of Fig. 4, integration should not be performed when the pointer 17 is anywhere on the closed-up part of the scale, as it introduces inaccuracies.

[Also in Division C7] A device for withdrawing samples from a bath of molten material, e.g. molten metal or glass, comprises a tube 4 adapted to have one end dipped into the bath and withdrawn after a time interval which is sufficient to ensure that the material which has penetrated into the interior of the tube has solidified, and a cutter 14a for cutting the tube at a point which contains the solidified material and a second cutter 14b for cutting at a point on the tube which has not been reached by the material. The tube is guided in rollers 5 and connected by a releasable clamp 7 to a belt 8 driven via a motor 11; the outer surface of the tube is covered by a coating of refractory material. The upper end of the tube is connected via a pipe 17 and a valve 20 to a nitrogen cylinder 23 and a vacuum pump 26. In operation, a stop member 15 is moved in order to allow the end of the tube to be inserted in to the molten material, e.g. steel pressurized nitrogen being fed down the tube in order to prevent slag 3 on the. surface of the steel from entering the tube. The valve 20 is then actuated so as to apply the vacuum source 26 to the tube and thereby assist the entry of the metal into the tube. After a certain time, the tube is raised and the cutters 14a, 14b operated in order to sever the solidified sample from the end of the tube; an additional cutter 14 is provided in order to separate the extreme end portion of the tube which may contain flaws. As the tube is used up additional lengths of tube may be screwed on to the upper end of the old tube.

Abstract: 653,928. Moulding wire-reinforced rubber tubes &c. POBEREJSKY,S. June 23, 1948, No. 16929. Convention date, July 5, 1947. [Class 87 (ii)] [Also in Group XXII] In a machine for helically coiling wire continuously, e.g. in making reinforced rubber tube, brake cable casings with or without plastic coverings, and sheathings, the axial twist produced in the wire by windinghelically on a mandrel is compensated for by rotating the mandrel in the direction opposite to the helixwinding direction once for each turn of the helix. The mandrel 3 has an axial passage 14 leading at the working end to a circumferential helical groove 16, and is rotated in end bearings 4, 5 by gears 6, 7 in synchronism with rolls 11 which feed the wire 12 through a guide die 13 into the passage 14. The grooved part 16 operates in a barrel 2 co-operating in forming the helix 19 which, since the mandrel 3 rotates in the opposite direction at an equal speed, emerges from the barrel 2 without axial rotation. In the form shown a stepped cylinder 20, freely mounted on the mandrel 3, cooperates with a screw-adjustable outer ring 21 to form a nozzle for extruding tube-forming material such as rubber, fed through a throat 26, directly on to the helix 19 as it is formed.
